"If therefore thine eye be single, thy whole body shall be full of light." (Matthew 6:22). During deep meditation, the single or spiritual eye becomes visible within the central part of the forehead. This omniscient eye is variously referred to in scriptures as the "third eye," "star of the east," "inner eye," "dove descending from heaven," "eye of shiva," "eye of intuition," and so on.
Thought is only memory.
Intuition is from the universal consciousness – spirit – mind.
The accumulation of insights, which are stored in the memory to be recalled later for the service of mankind, is called wisdom. Artificial knowledge, or ARTIFICIAL intelligence causes one to form or create many concepts. Conceptual knowing is what the Gnostics called false knowledge, or false knowing. What the Gnostics were saying was, why should any individual put their trust in conceptual knowing, which is always changing, when the individual could experience true knowledge, or UNDERSTANDING, of the intuitive and spiritual state which never changes and therefore does not create fear and uncertainty.
The Greeks sought "insights" and "wisdom," which makes them appear "intellectual." Intellectual capacity was not their goal. Self-realization and enlightenment were their goal and purpose in life; insight and wisdom are a NATURAL BY-PRODUCT (Seek ye first the kingdom and KNOW-THY-SELF mean the same thing).
"But the "helper," the (inner) "Holy Spirit whom the Father will "send" (uncover) in my name, he will teach you all things, and bring to your remembrance all things that I say to you."
-Jesus, John 14:26
For I will give you a mouth and "wisdom" which all your adversaries will not be able to contradict or resist.
-Jesus, Luke 21:15
Sometimes intuition is called an "original thought," or divine inspiration. With intuition you learn "how" to "think" instead of just "what" to "think." Intuition is superior to thinking; thinking is just the rapid recalling of stored information from memory.
When one is lost in thought there will be no insights; when one controls the brain and can stop thinking even for a short while, "insights" will come into being.
Science, technology and medicine can benefit from "insights." They will not benefit from thought or "thinking" (speculation, theories, and concepts.)
